' To @ZZ whom, it may concern.-

Be it known that I,I WILLIAM F. HUNT, a citizen of the United States,residing at New York, (West New Brightom) in the county of Richmond andState of New York, have invented an Improvement in Conveyers for Ooal,Ore, and other Materials, of which the following is a specification.

Conveyer-buckets have been connected up 1o in endless series, therebeing a chain at each side or else a rope or other device with suitableconnections upon which the gravitybuckets" are pivoted, and thesebuckets have been dumped at the desired place and sometimes have beenemployed for delivering coal at one place to a furnace and taking up theashes and discharging them at another place. In order to allow thesebuckets to hang freely by gravity and turn upon their Apivots as the zodirection of the conveyer may change, it has been necessary to allowasmall space between one bucket and thenext, and where the material hasbeen delivered from a spout or chute such material has passed betweenone bucket z5 and the next to a greateror less extent, and

lips have been provided upon the edges of the buckets to overlap oneanother,.and these lips generally being rigid have required to bechanged in the direction of the lap according 3o to the direction ofmotion of the conveyer in relation to the lap of the lips.

The present invention relates to movable lips hinged upon the bucketsapproximately in line with the inner edges in such a Inanner that eachlip is free to rise at the outer edge by contact with the lip of theadjacent bucket sufficiently for the bucket to clear the lip of theadjacent bucket, and means are provided to limit the motion of the lipas it 4o rises and also asit falls after the adjacent bucket passes outof contact with it and also for returning the lips to a normal position.

In the drawings, Figure l is a longitudinal section illustrating thegeneral character of 4 5 the present invention. Fig. 2 is a similarsection illustrating the present invention in one of the different formsin which it may be used, and Fig. 3 is a plan view showing the corner ofone of the buckets fitted with a hanging 5o weight to return the lip toits normal position.

The buckets A are formed of any desired size or shape and provided withpivots at 2, upon which the buckets hang by gravity from the chains orconnecting-ropes B, which pass one at each side of the buckets, so as toconnectthem up in endless series, and the chains are provided withrollers or wheels, E running upon stationary tracks, as usual; and Iremark that the present invention is available with gravity-buckets thatare connected up 6o in endless series between chains or ropes andadapted to receive coal, ore, ashes, or ,other material at one place anddeliver the same at another place. The lips C instead of being rigid arepivoted at adjacent to the edges of the buckets and approximately inline with the inner edges of said lips, and they are supported at aslightly-inclinedposition,or nearly horizontal, in any suitable manner,and one lip laps slight-ly upon the other, so that any 7o material thatmight otherwise fall between one bucket and the next is diverted by thelips into one or the other of the adjacent buckets and cannot fallbetween such buckets.

I find it advantageous to pivot the lips closely adjacent to but Withinthe edges G of the buckets, so that such edges may form stops to limitthe downward movements of the lips.

I have represented in Fig. l lips C, that are 8o substantially similarupon the opposite edges of the'buckets, and in this figure isillustrated theV fact that one lip 'laps upon the other slightly, so aseectually to bridge over or close theaperture or space between onebucket and the next.

In Fig. 1 I have shown a spring l2 applied to each lip C, and saidsprings are each connected at one end to an arm on the pivot of the lipsand at their other ends to the buck- 9o ets, and said springs preventthe lips being lifted too far and oblige them to return to a normalposition.

If desired, a stationary lip 8 can be employed at one side of one bucketand a pivoted lip at the adjacent side of the adjoining bucket, asillustrated at C', Fig. 2. In this instance the pivoted lip is shown asabove the stationary lip and bridgingthe space between the buckets, andit is adapted to move either roo -in one direction orthe other by thecontact with its outer edge of the rigid lip 8, and the vrigid lip 8vmay be arranged to always approach the pivoted lip from below. Thepivoted lip C is, however, shown as adapted to swing in both directionsand be returned to a normal position, preferably slightly inclinedupward, and for thisvpurpose any suitable 4 nections for unitingthebuckets in endless` series, the combination with the buckets, of`

mechanism may be employed, `preferably a swinging Weight l on one end ofthe pivot A5, that will return the lip to its normalv position, but willallow such lip to yield either one way or the other way, according'tothe direction p of vapproach of theadjoining bucket or the lip thereof.With this lip C a stop 7 may be so -located as to limit the swing of thepivoted lip in such amanner that the weight 10 will exert su tlicientforce to return the pivoted lip to a normal position.

I claim as myv inventionl. In a conveyer having buckets and conlips,pivots for some ofthe lips approximately in line with the inner edges ofsaidlipsv for connecting said lips near theedgesof 'the buckets, andmeans for controlling the movements of said lips on their pivotsandreturn ing them to anormal position, substantially as specified. y v

and means for returning the lips to their normal positions after theyhave been swung on their pivots, substantially as specified.
